I sold something on eBay about a month ago and the person e-mails me today saying that they still have not received the item since it has been a month. They said if I have another one, I should send it or I should refund their money. It was a small planner (worth like 15.00) and I shipped it USPS first class mail. I said in my description that unless insurance is taken out, I will not be responsible for lost or stolen packages. So what should I do... I thinking that the person did not take out insurance and I shipped it and I have my receipt to show that I shipped it. I want to stick to my policy, but I am afraid of getting negative feedback....What should I do?
